Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-slip locking device to be mounted on the back side of a shoe in order to prevent a slip accident when walking on a slippery place such as a snowy road or a frozen road.

[0002]

2. Description of the Related Art On a snowy road due to snowfall or an icy road due to a decrease in temperature, it is dangerous to slip while wearing ordinary shoes and it is dangerous. Many special-purpose shoes, such as boots, that have an anti-slip effect on slippery roads are also manufactured and sold. However, if the weather suddenly deteriorates when you are walking in a place where there is no snow or freezing and snow or freezing occurs and the road surface becomes slippery, you are wearing normal shoes and you should not slip. No effect.

When there is a slight amount of snow left on the previous day, but it is fine on the day and there is a high possibility that the remaining snow will completely melt, wear rain boots or the like to go out and use it as a normal change. It is inconvenient to carry shoes. Therefore, there is known a portable non-slip locking device that is lightweight and easy to carry, and can be easily attached to a normal shoe for use.

As an example of such a slip stopper for a shoe, a slip cover as disclosed in JP-A-10-42901 has been proposed. FIG. 8 is a side view showing an embodiment of this conventional technique. In this non-slip cover, a shoe sole covering portion 1 shorter than the shoe sole length and a shoe sole covering portion 1
A tip locking portion 2 provided at the tip of the to lock the tip of the shoe,
The rear locking portion 3 that is locked to the heel of the shoe is integrally formed of a wear-resistant elastic body, and a plurality of anti-slip projections 14 are provided on the outer surface of the shoe sole covering portion 1 while protruding. A plurality of spikes 10 made of wear-resistant metal are fixed to the holes penetrating the shoe sole covering portion.

Further, a strip-shaped covering portion 8 is formed between the recessed holes 6 and 7 on the rear side of the shoe sole covering portion 1. The strip-like covering portion 8 also has a plurality of spikes 10 and anti-slip projections 14. Is provided.

[0006]

However, this conventional technique has various problems. First, it is rather dangerous to provide the non-slip coating portion 8 on the heel portion of the shoe as shown in FIG. When walking on snowy roads or frozen roads, which is practiced by many people in snowy countries, it is common knowledge that the weight of the heel should be kept as low as possible by landing from the tip of the shoe when landing. By providing the non-slip coating portion 8 on the heel portion as shown in FIG. 8, the user tends to put weight on the heel portion with peace of mind.

In the anti-slip cover shown in FIG. 8, however, the tip of the spike 10 has a male rivet shape, and the anti-slip projection 14 has a pointed V-shape. That is, both have very small contact areas with the road surface. this is,
Although it has a slight effect of piercing the surface of snow (hereinafter referred to as the spike effect), it lacks grip and is very slippery and dangerous on icy roads. Therefore, by providing the non-slip coating portion 8 on the heel portion, the user feels relieved to put weight on the heel portion, and there is a very high risk of slipping and falling.

Further, since the rear engaging portion of the anti-slip cover of FIG. 8 is integrally constructed by a three-dimensional curved surface,
When the shoe is attached, the rear locking portion is pulled backward toward the rear of the shoe, lacking elasticity, resulting in poor wearability.

Further, the front end locking portion and the rear locking portion of the anti-slip cover of FIG. 8 are integrally formed by a three-dimensional curved surface. To mold such a structure,
The production is difficult and costly because it requires complex and relatively expensive molds. In particular, in order to commercialize this kind of anti-slip cover, it is necessary to arrange at least large, medium, and small sizes so as to match the size of the shoe, and several relatively expensive molds matching these sizes are required. As a need, this also increases product costs.

Further, the front end locking portion 4 has two rows of locking portions having a recessed hole in the central portion, which are locked relatively near the central portion of the front end of the shoe. In such a structure, the tip locking portion 4 is displaced to the left or right while the person is actually wearing and walking, and the tip of the shoe is likely to project into the recessed hole 5 or the like next to it.

There is also known a technique for preventing the tip locking portion from shifting to the left and right. Utility model application No. 9-
In the slip stopper for shoes described in 10694, the tip fixing portion at the tip is formed in an annular shape. However, although such an annular tip fixing part can prevent lateral displacement, it is easily pulled into the tip of the shoe during walking because the rubber cord locked to the heel pulls it, causing damage to the shoe and the foot. It causes pain.

In view of the above-mentioned various problems, the present invention eliminates the possibility of slip accidents due to the weight of the heel of the shoe, and the locking device is fitted tightly in any direction of front, rear, left and right. (EN) It is an object to provide an inexpensive anti-slip fastener for shoes, which improves stability and stability of walking because it is always stably held in a fixed position without slipping and can be easily worn. To aim.

Another object of the present invention is to provide a non-slip locking device for shoes which can be manufactured very simply and at low cost.

Still another object of the present invention is to exert not only the spike effect but also the grip effect up to the toes, and also to cause slippage to the rear of the shoe, damage to the shoe, and pain in the foot. An object of the present invention is to provide an anti-slip locking device for shoes, which can prevent the shoe from biting into the shoe tip.

[0015]

In order to solve the above-mentioned problems, in the invention according to claim 1, a non-slip main body which is formed of an elastic body and abuts on the front part of the shoe sole, and the non-slip main body A front locking portion that extends integrally and is locked to the tip of the shoe; and a rear locking portion that extends integrally behind the anti-slip body and locks to the side surface of the shoe heel. In a slip stopper for a shoe, which comprises a plurality of spike metal fittings and a protrusion for grip provided on the lower surface of the slip stopper body,
The rear locking portion is formed of a flat heel strip that connects both rear ends of the main body portion in a horseshoe shape, and the front locking portion is a lateral strip that extends upward from both sides of the main body portion. And a pair of vertical strips extending in a curved manner from the middle portion of the horizontal strip toward both front ends of the main body.

As described above, in the shoe non-slip fastener of the present invention, since there is no portion that covers the heel bottom of the shoe, the user should carefully land on the shoe tip when walking on a snowy road. You can avoid the risk of walking and landing from the heel and falling like a conventional non-slip cover. Further, since the front locking portion is composed of a lateral strip of elastic material and a pair of vertical strips, the structure is not only simple, but also highly elastic, and a horseshoe-shaped strip that constitutes the rear locking portion. Since the elastic body is formed into a relatively narrow flat shape and has elasticity, it is extremely excellent in wearability. It is firmly fixed without slipping and has extremely excellent usability. Further, since the front and rear locking portions and the like are formed by the strips having a relatively narrow width, the material cost is low, and the cost is low in this respect as well. Also, due to its structure, it can be easily installed as if it were a slipper.

In the invention according to claim 2 of the present invention,
The main body portion, the front locking portion, and the rear locking portion are formed of a single elastic sheet body, and in the expanded state of the elastic sheet, the pair of vertical strips are provided from both sides of the front end of the main body portion. A pair of lateral arm pieces that extend forward so as to approach each other and that constitute the lateral strip, are joined together at the center, and the lateral strips further extend diagonally forward from both sides of the main body. The front locking portion is formed by integrally connecting both ends of the lateral arm piece and the free ends of the pair of tilt arm pieces from the deployed state. Thus, the present invention provides a non-slip shoe locking device that is extremely simple and inexpensive to manufacture.

Further, according to the invention of claim 3, a slip preventing groove is formed in a shoe toe portion, which is an important portion where the hind foot finally kicks up the road surface, in the lower portion of the longitudinal strip of the front engaging portion. It is formed so that it becomes a non-slip locking device for shoes that is easy to walk safely.

Further, in the invention according to claim 4, since the cross-sectional shape of the outer wall of each of the plurality of grip convex portions is formed substantially vertically, the slip stopper of the shoe excellent in the spike effect and the grip effect is formed. It can be a locking tool.

[0020]

BEST MODE FOR CARRYING OUT THE INVENTION === Structure of the Present Invention === An embodiment of the present invention will be described in detail below with reference to the accompanying drawings. 1 to 3 are a side view, a bottom view, and a plan view showing an embodiment of a slip stopper of the present invention. Both show the state of being worn on men's shoes. FIG. 4 is a schematic plan view of the non-slip fastener of the same embodiment in a state where it is not attached to shoes.

In order for the non-slip locking device of the present invention to be fitted tightly to the shoe and to more reliably prevent it from slipping off during use, preferably at least M, depending on the size of the shoe, Three sizes, L and LL, are provided. Also, as will be described in detail later, in order to be properly attached to each of the left and right shoes, the left shoe anti-slip fastener and the right shoe anti-slip fastener are manufactured in different shapes. It is preferable that each has an appropriate shape for each of the left and right shoes.

The non-slip locking device 10 comprises a non-slip body portion 12 that abuts on the front part of the shoe sole, a front locking portion 14 extending forward from the non-slip body portion, and a non-slip body portion 1.
2 and a rear locking portion 16 extending rearward. These are integrally formed of an elastic material such as soft rubber having a hardness of about 55 degrees. The front locking portion 14 is elastically locked to the shoe tip portion and the rear locking portion 16 is elastically locked to the shoe heel portion side surface, respectively, so that the non-slip locking device 10 as a whole does not move forward and backward and left and right. It is securely attached to the position.

The front locking member 14 is a lateral strip 14a.
And a vertical strip 14b. The lateral strips 14a are extended upward from both sides of the main body 12 and are locked so as to sandwich the front part of the shoe in a ring shape. There are two vertical strips 14b, and the horizontal strips 14b are respectively provided from the left and right sides of the front end portion of the main body 12.
a is extended to the middle part (apex part) of a and the lateral strip 14a
It comes into contact with the tip of the shoe from the front.

FIG. 3 clearly shows that the pair of vertical strips 14b are slightly curved to sandwich the shoe tip from the left and right. It is preferable that the maximum portion D of the distance between the pair of vertical strips 14b is precisely determined, and for example, M is 30 to 3 in accordance with the size of the slip stopper.
5 mm, L is 40 to 45 mm, and LL is 45 to 50 mm. By providing a pair of the vertical strips 14b, it is possible to prevent the entire slip-resistant main body 12 from shifting toward the rear of the shoe during use. In addition, since the pair of vertical strips 14b sandwiches the shoe tip from the left and right, it is possible to prevent the shoe tip from shifting to the left and right with the two longitudinal strips aligned. .

The rear locking member 16 is a flat strip (heel strip) extending from the left and right sides of the rear end of the main body 12 in a horseshoe shape. As shown in FIG. Elastically locked to. When the rear locking device 16 is locked at an appropriate height,
This is preferable because the body portion 12 does not float from the shoe sole and is more closely contacted.

A plurality of spike fittings 18 and a grip projection 20 are provided on the bottom surface of the non-slip body 12. The spike metal fitting 18 mainly exerts an effect of piercing a snowy road or a frozen road, that is, a spike effect. In order to prevent slipping on snowy roads and frozen roads, it is very important not only to have a spike effect, but also to have a grip effect for firmly catching the ground contact surface. In the non-slip locking device 10 of the present invention, the grip projection 20 exerts this grip effect.

A sectional view of the spike fitting 18 and the grip projection 20 is shown in FIG. In this embodiment, the spike fitting 1
No. 8 is a rivet with a cylindrical tip,
The head part of the rivet is the spike-embedded base 2 of the main body 12.
It is embedded in 6a. The spike-embedded base portion 26a also exhibits a grip effect as one of the grip projections.
Three types of planar shapes of the grip projection 20 are provided, that is, a round shape, a Y-shape, and a shape in which two Y-shapes are connected. However, all the projections 20 are integrally raised from the main body 12. Is formed. The cross-sectional shape of any of the planar-shaped convex portions 20 is such that the contour is vertical and the tip is not sharp. That is, the convex portion 20 having a round planar shape is
The whole is cylindrical.

The tip of the spike metal fitting 18 has a grip convex portion 2
If the length d (Fig. 5) protruding from the tip of 0 is too long, only the spike metal fitting 18 will come into contact with the ground, and the grip protrusion 20
Is not grounded and is dangerous. If it is too short, the spike effect will be lost. Therefore, d is preferably about 1 mm.

A detailed sectional view of the spike fitting 18 is shown in FIG. As can be seen from the figure, the cylindrical tip portion of the spike fitting 18 is inclined from the outer wall side toward the inner wall side, and has a very sharp structure. Therefore, it exerts a strong spike effect on snowy roads and frozen roads.
Further, if the number of spikes is too large, the load due to the weight is dispersed and it becomes difficult to pierce, and if it is too small, the spike effect becomes small. Therefore, it is necessary to set an appropriate number that is neither too large nor too small, depending on the size.

The grip convex portion 20 which has a grip effect is
In particular, a Y-shaped or a combination of two Y-shaped protrusions is provided in order to prevent slippage in all directions, not only in the front-back direction, but mainly in the position where the load is applied.
As described above, since the cross-sectional contours of the protrusions 20 are substantially vertical, the ground contact area is relatively large as a whole, and an effective grip effect like a studless tire is exhibited.
Further, in order to exert the grip effect, it is necessary to firmly grasp, store, and hold the snow in the space between the convex portion 20 and the spike fitting 18. In the case where only the grip convex portion having a sharp tip is provided, snow cannot be held in the space between the convex portions, so that a sufficient grip effect is not exhibited. In the grip convex portion 20 having a substantially vertical cross-sectional contour, the grip effect can be exhibited by firmly grasping and holding the snow in the space between them.

The front locking portion 14 shown in FIGS. 1 and 2.
An anti-slip groove 22 is formed on the lower portion of the vertical strip 14b for gripping the ground when kicking up the toe portion of the shoe. Due to the provision of the anti-slip groove 22, when the rear foot finally leaves the ground during walking, the ground can be firmly caught without slipping the toes. Therefore, walking stability and a sense of security can be obtained.

Further, in the embodiment shown in FIG. 2, the right foot shoe is equipped with the right anti-slip locking device. More preferably, the stop lock is manufactured. The left and right soles are curved or bent so that the center line of the sole extending from the center of the toes to the center of the heel bulges outward of the foot. The projecting portion 20 (and the spike metal fitting 18) is arranged so as to match the curve or bend. If you use a straight non-slip that does not bend or bend for both left and right, the grip protrusions are located inside the foot on both sides (from the center of the body).
The grip effect (and spike effect) is not exerted.

=== Manufacturing Method of the Present Invention === FIG. 7 is a plan view showing an unfolded state of the anti-slip fastener 10 of the above embodiment. As can be seen from the figure, the main parts of the anti-slip fastener 10 (the anti-slip body portion 12, the front engaging portion 14, and the rear engaging portion 16) are formed from a single elastic sheet.

A lateral strip 14 which constitutes the front locking portion 14.
a is composed of a lateral arm piece 14c and a tilted arm piece 14d in the unfolded state prior to the coupling.
c extends in a straight line in the left-right direction with the united portion C of the pair of vertical strips 14b as the central portion, and the inclined arm pieces 14d extend obliquely forward from the left and right sides of the anti-slip body portion 12. It constitutes the root of the lateral strip 14a. The left and right ends of the lateral arm piece 14c and the free ends on both sides of the inclined arm piece are joined by joining means such as riveting at the joining portion 24 to obtain a completed product as shown in FIG.

In the manufacturing procedure of the non-slip locking device 10 to the unfolded state, first, the concave portion for forming the grip convex portion 20 is provided inside the portion that defines the anti-slip main body portion 12 in the above developed view. A mold is prepared, and the spike metal fitting 18 is arranged at a predetermined position of the mold. Next, a sheet made of soft rubber having a plane rectangular shape larger than the above developed view is placed above the mold.
Next, the mold is closed for a predetermined time, melted by hot pressing, and the grip projection 20 is formed on the bottom surface of the non-slip body portion 12, and at the same time, the spike metal fitting 18 is embedded in a predetermined position of the body portion 12. In FIG. 7, the spike-embedded base 2
The upper surface side raised portion 26b of 6a is raised slightly in an annular shape in order to bury the head portion of the spike mold 18. The raised portion 26b is an important portion that exerts an anti-slip effect on the shoe sole during mounting while contacting the shoe sole.

=== Method of Use of the Present Invention === To mount the non-slip locking device 10, the lateral strip 14a is used.
And insert the shoe toe into the front locking part 14 consisting of the vertical direction band 14b, and then pinch the rear locking part (the heel band) 16 by hand, and pull it up at an appropriate height on the side of the shoe heel to wear it. To do. It can be worn with one hand just as if it were a slipper, and it can be worn very easily, so in the event of sudden snowfall,
Easy to use even in extremely cold conditions.

As described in detail above, the spike effect of the spike metal fitting 18 and the grip effect of the grip projection 20 work sufficiently to prevent slippage during walking while wearing the device. Since there is no anti-slip structure on the bottom of the heel of the shoe, the possibility of slipping accidents due to landing from the heel in many cases in anticipation of the anti-slip effect on the heel is low. Further, due to the structure of the front engaging portion 14, the slip stopper 10 is not displaced to the rear of the shoe during walking, causing pain in the foot, and the main body portion 12 is not displaced toward the arch. In addition, by providing the anti-slip groove 22, a grip effect for achieving safe walking when kicking up the ground immediately before the rear foot leaves the ground during walking was obtained.

In order to remove the shoes, in the reverse order of the wearing, first, the rear engaging portion 16 engaged with the side surface of the shoe heel is pinched by hand, and pulled out slightly from the heel to remove it from the heel. The front part is automatically disengaged by removing the rear part, but if it is not disengaged, the front end part may be slightly raised and the front engaging part 14 may be pinched by hand and lifted.

[0039]

According to the non-slip fastener of the present invention,
Since there is no part that covers the bottom of the heel of the shoe, the user should walk carefully while walking on a snowy road, etc. as if landing from the tip of the shoe, and like a conventional anti-slip cover, the risk of landing from the heel and falling. You can avoid sex. Further, since the front locking portion is composed of a lateral strip of elastic material and a pair of vertical strips, the structure is not only simple, but also highly elastic, and a horseshoe-shaped strip that constitutes the rear locking portion. Since it is formed into a relatively narrow flat shape of an elastic body and has elasticity, it is extremely excellent in wearing. It is firmly fixed without slipping and has extremely excellent usability. Furthermore,
Since the front and rear locking portions are formed of strips having a relatively narrow width, the material cost is low, and the cost is low in this respect as well. Also, due to its structure, it can be easily installed as if it were a slipper.

Due to the above, the non-slip locking device of the present invention can be manufactured extremely easily and inexpensively.
